Find the value of x. if necessary, round to the nearest tenth a=47sq in
kipiarov [429]

the picture in the attached figure


we know that

area of the triangle is equal to

A=(b*h)/2


in this problem

A=47 in²

b=x

h=x

so

47=x*x/2 \\  x^{2} =94 \\ x= \sqrt{94}  \\ x=9.69 in \\ x=9.7in

therefore

the answer is

malfutka [58]

Answer:

Mean = 30

standard Deviation = 2.74

Step-by-step explanation:

Formula

mean = np

Standard Deviation = \sqrt{npq}

from the question = 40

P = 75% or 0.75

q = 1 - p = 1 - 75% or 1 - 0.75

To find mean

mean = 40 x 0.75

           = 30

For Standard Deviation (SD)

Standard Deviation = \sqrt{npq}

       = \sqrt{40 X 0.75 X 0.25

      = \sqrt{7.5}

:. Standard  Deviation       = 2.74
